E5612 and E5624 controller-drive trays and EF560 flash array: Optional DC power connector cables and source wires

The E5612 and E5624 controller-drive trays and the EF560 flash array are shipped with –48-VDC power connector cables if the DC power option is ordered. The –48-VDC power connector cable plugs into the DC power connector on the rear of the controller-drive tray or flash array. The three source wires on the other end of the power connector cable connect the controller-drive tray to centralized DC power plant equipment, typically through a bus bar above the cabinet.

Warning: (W12) Risk of electrical shock – This unit has more than one power source. To remove all power from the unit, all DC MAINS must be disconnected by removing all power connectors (item 4 below) from the power supplies.
1. Supply (negative), brown wire, –48 VDC
2. Return (positive), blue wire
3. Ground, green and yellow wire
4. DC power connector
Warning: (W14) Risk of bodily injury – A qualified service person is required to make the DC power connection according to NEC and CEC guidelines.

Two (or, optionally, four) DC power connector cables are provided with each controller-drive tray or flash array. Two DC power connectors are on the two DC power supplies on the rear of each controller-drive tray or flash array if additional redundancy is required.

Note: You do not need to connect the second DC power connection on the DC power supplies of the controller-drive tray or flash array. The second DC power connection is provided for additional redundancy only and can be connected to a second DC power bus.
